water.” Also one cite says,” It is used by crime scene investigators to discover spots of blood, even spots that may have been washed.” The last cite writes,” It was concluded that an inverse relationship exists between surface temperature and the reaction rate of the Luminol test.” Our question/ purpose was,” How does temperature affect luminol?” My hypothesis was that I thought that the warm water would affect the luminol more than the cold water. For this experiment, we needed a few materials.

nitrate cation using the iron sulfate test. At this point it was hypothesized that the compound was calcium nitrate. Reactivity tests and quantitative analysis comparing the unknown compound with calcium nitrate supported this hypothesis. Synthesis reactions were then carried out and analyzed. Introduction

Abstract The goal of the experiment was to observe a typical enzyme reaction, also, to be able to find certain conditions that either slow down or accelerate enzyme activity. An enzyme is a biological catalyst that is usually categorized as a protein. One of their roles is to digest food and boost metabolism. In the experiments, the enzyme is a substance complex product; The cofactor is a metallic ion that aids in the reaction. The chemical equation is H2O2 --------peroxide--------- H2O + O2; where H2O2

First of all, the reactions that occur in the human body could not happen without the presence of macromolecules. The four macromolecules, proteins, lipids, carbohydrates and nucleic acids, make up everything in the human body. These important macromolecules could not be formed without the chemical reaction of dehydration synthesis. All four of the macromolecules that make up life are formed by the reaction of dehydration synthesis, also known as condensation. As seen in figure 1, water is extracted

enzyme affect the reaction? The enzyme used in this investigation was peroxidase. The enzyme concentration was changed by making the enzyme more concentrated than was it is.The effect of enzyme concentration on the reaction was measured by the color change per minute. The purpose was using the original procedure as the control group. The dependent variable was used by Keywords: Lorem, ipsum, dolor  Introduction Enzymes are proteins, in which it speeds up the chemical reaction. Enzymes can be

that are not caused by changes in the DNA sequence but they are triggered by chemical reactions that activate and deactivate parts of the genome and in specific locations. Therefore, epigenetics is the study of chemical reactions and factors that influence them. Hypothetically, epigenetics has the huge potential in terms of the uncovering genetic development of organisms, including humans, and the impact of chemical reactions that occur under the impact of various factors and affect genome activation

Introduction: Enzymes are proteins that start chemical reactions. Enzymes are found in anywhere from saliva, small intestine and stomach. The enzymes break down food and other substances into smaller particles. Depending on the living conditions of the enzymes they will speed up, slow down and or produce no reaction. Enzymes serve as catalyst to produce a natural reaction. Those enzymes that live in the stomach have a high acidic concentration. The enzymes that live in the small intestine have

food industry. It is understandable to think that chemistry and food are not closely related, but chemical processes and interactions play a major role in almost all the food products we ingest today. All foods have chemicals in it, whether it is natural or not. In cooking, when a food turns from one thing to another (like bread turning into toast, or runny egg yolk turning into solid egg), a chemical change has occurred. This process is irreversible and energy has been used. Food chemistry, like

purpose of this 3 part experiment is to determine cations via various tests, such as identifying cations with forming precipitates (qualitative analysis tests) or identifying cations with performing cation flame tests. Part A was mixing various chemicals to form specific types of precipitates that indicated the presence of a Lead cation or a Silver cation. Part B was similar to Part A, but Part B contained a false positive of whether the cation was Barium or Calcium (both had white precipitates)

called catalase and how its rate of reaction was dependent on the specific conditions surrounding it. The research question provided for this lab was: “How do pH, temperature and surface area affect the action of catalase?” Introduction In order to understand how enzymes work, it is important to know what a catalyst is. A catalyst is a substance that enhances the rate of a chemical reaction without undergoing any irreversible chemical change at the end of the reaction (Chemicool). An enzyme is a protein
